Nvidia had a slew of great announcements at SIGGRAPH 2008
this year and below are summary hightlights

Nvidia First to Ship OpenGL 3.0

Nvidia at Siggraph announced the beta drivers for the new
OpenGL 3.0 standard, implementing the cross-platform, 3D
graphics standard API and the GLSL 1.30 shading language
for both Windows XP and Windows Vista on selected GeForce
and Quadro boards.

With these drivers any software developer can now explore
the capabilities of the new OpenGL 3.0 standard on Windows
systems. OpenGL
3.0 is a significant advancement for professional
graphics and Nvidia is driving this standard forward, beating
ATI (a division of AMD) to the punch with working drivers
to support popular GeForce and Quadro GPU cards. New in OpenGL
3.0 are vertex array objects, enhanced vertex buffer objects,
32-bit floating-point textures, render and depth buffers,
new texture compression schemes, sRGB frame buffers, and
an upgraded shading language. More information on OpenGL
3.0 can be found
here.

At three bounces of light performance was measured at up
to
30fps
(frames/sec.)
at HD resolutions of 1920x1080 for an image-based lighting
paint shader, ray traced shadows, reflections and refractions
running on four next-generation Quadro GPUs in an Nvidia Quadro Plex 2100 D4 Visual Computing System (VCS).

This type of development portends to exciting things in
the world of CAD and 3D in the not-too-distant future.

Nvidia
Quadro FX

Nvidia also announced at Siggraph the new Nvidia Quadro
FX notebook family of ultra high-performance graphics processors.
Designed for the mobile workstation, Nvidia introduced a
new family of Quadro FX mobile GPUs featuring Nvidia an CUDA
Parallel Computing Processor.

Apple's MacBook
Pro is generally touted as a workstation-class,
industry leading mobile computer. With a new model just
around the corner it will be interesting to see if Apple adopts
the new Quadro FX series of GPUs.

Finally in other Nvidia Siggraph news the graphics company
has announced new Nvidia Quadro Plex Systems for the geoscience
and scientific visualization markets. Designed to handle
very large data sets Quadro Plex systems gang together multiple
GPU systems into a single box (some for rack-mounting) that
sit deskside. Quadro Plex systems start at 10,750.USD and
will be available in September. Current operating system
support includes Windows XP and 64-bit edition, Linux and
Solaris x86. The system interface for hooking up the Quadro
Plex unit is a standard PCIe x8 slot or x16 slot.
